PORTABLE STOVE.

To all 11i/omit may concern.' 4

Be it knownthat I, CLARENCE O. SHEL- l DON, a citizen of the UnitedStates, and a yio lid

supplying heat in orchards to resident of Donna, in the county ofHidalgo and State of Texas, have invented certain new and usefulImprovements in lPortable Stoves, of which the following is aspeciication.

This invention relates to improvements in portable stoves.

The invention more particularly relates to an oil stove adapted forOut-of-door use for prevent the fruitI from being damaged by frost, orfor a similar purpose.

The general object of the invention is to provide a stove of thischaracter which is exceedingly efficient and economical in operation.

It is also an object of the invention that the stove be durable andinexpensive to manufacture.

A further and important object of the invention is that the stove beadapted to continuously operate without attention.

y A still further object of the invention is that parts of the stovesubject to deteriora-- tion maybe renewable.

Other objects, and objects relating to details of construction,combination and arrangement of parts will hereinafter appear in thedetailed description to follow.

The invention is illustrated by way of o X- ample in the accompanyingdrawmgs, 1n which Figure 1 is a central vertical sectlonal view of astove constructed in accordance with the present invention.

Figure 2 isa bottom plan view of tho stove cover.

Referring to the drawings generally R 1ndicates a receptacle or tank inwhich fuel o1l for the stove may be retained, C mdlcates the covertherefor and C the chlmney.

The receptacle R is preferabl circular 1n cross section 'and taperstowar its bottom and has its upper edge turned outwardly to form a bead10.

The cover C consists in a frusto-conicalv sheet body portion 11 which isprovided with a suitable opening'at its upper end to receive a nipple'12, said nipple having a lip 13 formed upon its lower end by which thesame may be secured to the cover C. Preferably the lip 13 of the n1ppleshould to telescope 1922. serial No. 558,043.

be welded to the cover C. The lower peripheral edge of the cover is bentor crimped upon itself to provide the flange extension 14 of doublethickness as shown and to provide the downwardly depending skirt or lip15 which is adapted to be received by the upper end of the receptacle Rand the flange 14 adapted to seat upon the bead 10 of the receptacle Rwhereby to removably support the cover C in an eilicient manner. The chimney C comprises the two casting sections 16 and 17 and .the sheetmetal section 18. The casting 16 consists of'a cylindrical lower endportion 19 which is adapted the nipple 12 extending from the cover C anda perforated bowl-shaped portion' 20 which terminates at its upper end1n a cylindrical portion 21 and said cylindrical portion having formedabout its lower end a supporting flange 22.

The cylindrical portion 21 is adapted to be telescoped by the sheetmetal section 18 and said sheet metal section 18 being supported againstdownward movement by the fiange 22. The casting 17 consists in a bodyportion 24 which tapers toward its upper end and which terminates at itslower end in a cylindrical extension 25 which is adapted to telescopethe upper end of the section 18. The upper end of the body portion 24 ofthe casting 17 terminates in a reduced cylindrical portion 26 and whichmay be telescoped by ordinary stove piping or the like in or der toextend the chimney as indicated at 27. Also when the stove is not in usethere is provided a closure for the upper end of the casting 17 whichconsists in a cap indicated 'by dotted lines at 28.

Within the receptacle R there depends a skirt S, said skirt beingsemi-circular in cross section and tapering toward its lower end andbeing secured at its upper end to the body portion of the cover C by themeans of rivets or the like as indicated at 29. The longitudinal edgesof the skirt are in spaced relation with the side wall of the receptacleas indicated at. 3() and the lower end of the skirtvis in spaced"relation with the bottom of the receptacle as indicated at 31. Upon thebody portion of the cover at a point registering with the enclosureformed by the skirt S there is hinged a flap door D, said doorconsisting in an annular member 32 which has its inner periphery formedwith a groove adapted for enclosing l no y a circular plate 33. Theplate 33 carries a handle 34 and said plate together with the bodyportion 11 of the cover are formed with openings as illustrated wherebyentrance of air into thereceptacle R may be effected. The amount of air'may be closely regulated by manipulating the plate 33. Theannular member32 is hinged to the body portion 11 of the cover as at 35 and adapted tobe swung upwardly and thus to serve as an opening for filling thereceptacle with fuel oil.

From the inner side of the body portion 11 of cover C -there projects aplurality of studs or pins 36 which are arranged in circular formationand adapted to support a baille plate or divisional plate P againstupward or downward movement through the cooperating lugs or hooks 37.The plate P may be easily removed or positioned in an obvious manner.Diametrically opposite to the skirt S, the pflate has aI peripheralportion or a segment cut therefrom to provide .la passageway 37. l

In the use of the present stove, the receptacle R is filled with oil toa suitable level, and if this oil is heavy such as crude oil or thelike, then the pla-te P should be removed. Now a small quantity ofgasoline may be poured through the opening adorded bythe door D and uponthe oil within the enclosure afforded bv the skirt S. Upon igniting thisgasoline, the llames thereof will pass around the longitudinal edges ofthe skirt S and during this passage will be, substantially smothered.The hot gases generated by this flame quickly carry the fumes arisingfrom the oil within the receptacle upwardly and through the nipple 12 oroutlet passage of the cover C. Immediately upon these fumes passing into4the upper end of the casting 16 air rushes in through the perforatedportion 20 of this casting and supplies the oxygen necessary forcombustion ,of the fumes. At this point slight explosions will takeplace and the section 18 of the chimney will become highly heated. Theinrush of air through the perforated portion 20 of the casting 16prevents any clogging of the perforations of this portion. Also theexplosions which occur in the upper end of the casting or within thesection' 18 further eliminate any possibility of clogging of thisperforated portion of the 'cast. ing'16. vWhen starting the stove it isnecessary to apply a torch or light to the perforated portion 20 of thecasting 16 in order that'ignition of the fumes may be had. After thestove .is once started the same will operate continuously and withoutundue ex- 4plosions to lift the oil from the receptacle R.

When it is desired to use coal oil as a liquid fuel or other similardistillate, the plate P is placed in its position and with thisercomprisin rangement the fumes passing from the enclosure afforded bythe skirt S- must pass beneath the plate P until they reach thepassageway' 37 afforded thereby before they may escape from the cover C.This further insures to smother the flame maintained within theenclosure afforded by the skirt D. In other words, this flame must notbe permitted to continue and pass out through the cover C, for thereason that under these conditions the stove would unduly smoke andoperate at a very low efficiency.

It is believed from the construction shown of the chimney C thatl itbecomes obvious 'that the section 18 is easily removable. The castings16 and 17 are not subjected to great Aheat like the sheet metal section18 and need not be renewed. The stove-pipe 27 may be of any lengthdesired. Also the chimney construction, Aas shown, is-weather proof andby placing the cap' 28 over the upper end of casting 17. the stove maybe permitted to remain in the fields for any period of time without harmthereto. Furthermore with this arrangement the stove may be filled withoil and prepared ready for operation at any moments notice, that is,made readyfby removal of the cap 28 and placing the stove-pipe extension27 upon the upper end of the casting 17.

While I have shown and described, the preferred form of my invention,I'wish it to be understood that I am aware of the fact that theconstruction, combination and arrangement of parts may be changed bythose skilled in the art without departing from the spirit of theinvention as indicated by the appended claims.
